BUILDING STAND Application fi led August 21, 1930. Serial No. 476,927.

This invention relates to building stands such as are used to position the micas and foils duringassembly of a capacitor stack and has for its object to lower the labor cost of stack production. Another object is todo away with the necessity for maintaining many such building stands in stock, thereby reducing tool costs. V 1

, Heretofore it has been customary to'make the required number of building standslfor each size stack needed. Frequently orders are received which require stacks of a different size from those forwhich-stands have already been made up and the tool cost for such special jobs has been high, owing to necessity of making up stack building stands for each size stack required.

According to this invention these costs are reduced by making it possible to use the same stands for different sizes of stacks Without the necessity of using measuring instruments and the liketotest the adjustedyposition of the stand for a particular size stack desired. The labor ordinarily used in stack assembly is not generally sufiicientlyskilled to use measuring instruments so that adjustments could not be conveniently made Which would require the use of any such precision.

The building stand of this inventionis intended to take the place of the prior art nonadjustable stands of the type like that shown, for example, in Figs. 1 and 2 of Pickard 1,706,816 March" 26, 1929.

Each stand includes a graduated or gauged ported on a work bench orother support by the legs shown which may rest on the bottom of the inside of the waxing tray. On ioundation member 10 are two stackrsupportililg m m er 1 a 1. one o h e 123 th embodi nt st at d, i h is made dustable to vary its separation from the other sta kupp r m mbe canes eeu' rigidly to base 10.

Some of the pr ncipal standard sizes for" mica sections employed today include the following, in inches: 1 x 1%, 1 x 1 ,;1 X 2, x1 /2, x /l, xe%- With the present invention' it is no longer necessary to delay erection otstacks involv ing some unusual size stack while the building stands are being built .or even to change stands in front of the operatives; and itis no longer necessary to maintain the previous investment in a large number ,of building" 011 memb rs 11 and '12 are mounted restands for each size mica, since the present invention is adapted for a wide variety of mica sizes, the slots 15 being as close together as may be desired.

To change the adjustment of the stand, making it adapted for another size, the wing nut 20 is loosened and the adjustable stacksupporting member 12 is raised from the foundation member 10 so that the locking member '16 is moved out of the slots 15 while clamping bolt 19 remains in slot 18. The member 12 with its plate 16 then is moved left or right along base 10 until the legs of plate 16 are above the proper pair of slots 15, when 12 and 16 are lowered so that the U-legs enter the slots and nut 20 is screwed up to clamp parts 10 and 12 together between said nut and the screw-head of bolt 19.

If desired, a sample stack or mica sheet of the size for which the stand is to be adjusted, may be placed between the cut-out portions of guides or posts 13, 14 as a gage for the adjusted positions of member 12 and plate-16.

In this way no measuring tools other than the mica itself as a gage will be necessary in order to know that the stand is adapted for a given size stack or a given size mica. As shown in Figs. 3 and 4, in building up the stack, when the first mica sheet 21 is placed on the two stack-supporting members 11, 12, said sheet bridges over the space between members 11 and 12 and over base 10, and so with the superposed foils and micas. The Widths of members 11, 12, and the locations thereon of posts 13, 14, and the locations of slots 15 in base 10, are such, however, that micas of shortest linear dimension may be used when supports 13, let abut against one another, i. e., when there is no space between them bridged by the elements of the stack under construction. As first above indicated, the base-member slots 15, aside from their preferred construction involving interlocking with the movable stack-supporting member 12, constitute gages or graduations indicating the desired positions of member 12 independently of the use of a sample stack or mica sheet placed as a gage between posts 13l4. When, as preferred, the interlocking slots 15 are employed, they interlock member 12 from movement along base member 10 away from the other stack-supporting member 11, and bolt 19 etc. clamp member 12 in its interlocked position from movement away from base-member 10.
